Abstract

a. L'invention concerne un procédé pour la fabrication d'aldéhydes aromatiques à partir de l'acide aromatique correspondant. b. Le procédé comporte les étapes suivantes : réaction de l'aride aromatique avec du chlorocarbonate d'éthyl ou d'isobutyl en présence d'une base et d'un solvant inerte, ce qui donne l'anhydride correspondant, hydrogénation directe de l'anhydride en aldéhyde en présence d'un catalyseur palladium/sulfate de baryum. c. Ce procédé permet d'obtenir dans de très bonnes conditions de prix et de rendement les aldéhydes aromatiques et en particulier le benzaldéhyde et ses dérivés.at. The invention relates to a process for the production of aromatic aldehydes from the corresponding aromatic acid. b. The process comprises the following steps: reaction of the aromatic arid with ethyl or isobutyl chlorocarbonate in the presence of a base and an inert solvent, which gives the corresponding anhydride, direct hydrogenation of the anhydride in aldehyde in the presence of a palladium / barium sulfate catalyst. vs. This process makes it possible to obtain aromatic aldehydes and in particular benzaldehyde and its derivatives under very good conditions of price and yield.
